Supersweet corn cultivars, homozygous for the recessive shrunken-2 (sh2) allele, were compared in field trials at 3 separate planting dates, in 1987-88, at Bundaberg, Queensland. Sensory quality of the 6 sh2 cultivars and a standard cultivar, homozygous for the recessive sugary (su) allele, were compared in a separate experiment. Because of higher yields and larger cobs produced in midwinter planting, and the higher incidence of disease and heat stress encountered in spring or late spring plantings, it is proposed that sh2 cultivar production should be limited to a midwinter sowing in subtropical Bundaberg. Taste panel testing indicated preference for all sh2 cultivars over the standard su cultivar in terms of both general acceptability and texture, and the su cultivar was rated least sweet. Snosweet was rated highest in terms of both general acceptability and texture and was also rated the sweetest cultivar.
